dm: Add base driver model support Add driver model functionality for generic board. This includes data structures and base code for registering devices and uclasses (groups of devices with the same purpose, e.g. all I2C ports will be in the same uclass). The feature is enabled with CONFIG_DM.

dm: Provide a function to scan child FDT nodes At present only root nodes in the device tree are scanned for devices. But some devices can have children. For example a SPI bus may have several children for each of its chip selects. Add a function which scans subnodes and binds devices for each one. This can be used for the root node scan also, so change it. A device can call this function in its bind() or probe() methods to bind its children. Signed-off-by: Simon Glass <sjg@chromium.org>

UCLASS_TEST_BUS,
dm: sandbox: Add a SPI emulation uclass U-Boot includes a SPI emulation driver already but it is not explicit, and is hidden in the SPI flash code. Conceptually with sandbox's SPI implementation we have a layer which creates SPI bus transitions and a layer which interprets them, currently only for SPI flash. The latter is actually an emulation, and it should be possible to add more than one emulation - not just SPI flash. Add a SPI emulation uclass so that other emulations can be plugged in to support different types of emulated devices on difference buses/chip selects.

UCLASS_GPIO, /* Bank of general-purpose I/O pins */
dm: Add a uclass for serial devices Serial devices support simple byte input/output and a few operations to find out whether data is available. Add a basic uclass for serial devices to be used by drivers that are converted to driver model. Signed-off-by: Simon Glass <sjg@chromium.org>

UCLASS_SERIAL, /* Serial UART */
dm: spi: Add a uclass for SPI Add a uclass which provides access to SPI buses and includes operations required by SPI. For a time driver model will need to co-exist with the legacy SPI interface so some parts of the header file are changed depending on which is in use. The exports are adjusted also since some functions are not available with driver model. Boards must define CONFIG_DM_SPI to use driver model for SPI.

dm: sf: Add a uclass for SPI flash Add a driver model uclass for SPI flash which supports the common operations (read, write, erase). Since we must keep support for the non-dm interface, some modification of the spi_flash header is required. CONFIG_DM_SPI_FLASH is used to enable driver model for SPI flash.
